Description

[Detailed explanation of the invention] In the conventional self-propelled tea picker of this type, a separate support is provided on one side of the gate-shaped vehicle body, and this is connected to several groove wheels in front and behind the lifting platform. The reaper is held by the vehicle body, and one end of the reaper is attached to the lifting platform to support the reaper on the vehicle body.

Therefore, since there is only one support, the reaper tends to freely swing back and forth using the support as a fulcrum. For this reason, the operator must constantly adjust the swing of the reaper with the operating handle of the reaper, which causes great fatigue for the operator, and requires workers to stand on both sides of the machine. 2
There were drawbacks such as the need to operate the reaper manually.

Therefore, in order to eliminate the above-mentioned defects, the present invention utilizes two vertical rods in one side frame of the gate-type vehicle body,
A lifting platform is fitted onto the two vertical rods so as to be movable up and down without providing the support as a separate part, and one end of the reaper is attached to the lifting platform to eliminate swinging of the reaper, and at the same time, The reaper is made to move up and down lightly and smoothly along the vertical rod, and on the other hand, a horizontal adjustment shaft is horizontally mounted on the middle part of the reaper, and a hanger is attached to the adjustment shaft so that the horizontal movement can be adjusted. Adjust the ground height of the reaper by moving the sling up and down with the hoist, move the sling left and right along the adjustment shaft to adjust the lateral inclination angle of the reaper, and raise the bottom of the reaper. This invention relates to a reaping machine mounting device for a self-propelled tea plucking machine that allows the reaping machine to be hung in accordance with the shape of the upper surface of a tea ridge.

To explain the structure of one embodiment of the present invention shown in the drawings, 1 is a gate-shaped vehicle body that straddles a tea ridge, with a driving wheel 2 pivoted on the rear part of the first side and a control handle 3 attached to the front part of the first side.

The vertical rod 6 is held between the vertical rods 6 and 7, and the groove wheel 15 is engaged with the rear portion of the vertical rod 7, so that the elevating platform 11 is fitted to the vertical rods 6 and 7 so as to be able to move only up and down. Reference numeral 16 denotes a horizontal shaft protruding from the front of the lower end of the lifting table 11. Its base end is pivotally supported on the lifting table 11 by a support shaft 17, and a support piece 18 is provided above the base end, and the horizontal shaft 16 is opposed to the corresponding piece 18. Then, install the adjustment bolt 19 screwed into the screw hole of the lifting platform 11 .

A support rod 20 is rotatably fitted into a vertical tube 21 in the middle of the vehicle body 1, and a hoist 22 is attached to the tip thereof. 23 is the handle of the winder 22; 24
is a hanging spring, and a hanging metal 25 is attached to the tip of the hanging spring, and a knob bolt 26 is screwed into the threaded hole of the hanging metal 25.

A shows a rotary type reaper located approximately in one half of the vehicle body 1, and 27 is an oblong machine casing with its front open, and the bottom surface is formed into a concave arc shape to match the upper surface of the brown furrow. A take-out gutter 28 is provided protruding from the rear side,
The rotary blades 29 on both sides are pivoted in the front part of the machine casing 27, and a conveyance chain 30 is installed in the rear part. 31,3
Reference numeral 2 designates operating handles on both sides that are attached to the center and one side of the machine casing 27 so as to be adjustable in vertical movement, and 33 is a reaper stabilizing plate connected to the rear of the bottom plate of the machine casing 27. Thus, a longitudinal mounting tube 34 provided on the side of the bottom surface 1 of the machine casing 27 is rotatably fitted onto the horizontal shaft 16, and a horizontal adjustment shaft is installed horizontally over the center of the machine casing 27. Fit the hanger 25 to the bolt 25 so that it can move left and right, and then tighten the bolt 26 with a knob at the appropriate position.
Tighten and fix the hanging metal 25 to the adjustment shaft 35 with
The wind turbine shaft of the blower 9 and the power intake shafts of the rotary blade 29 and the conveyance chain 30 are connected by a transmission mechanism.

36 is a pressure-feeding duct that communicates the outlet of the blower 9 with the inlet of the take-out gutter 28; 37 is a blow-up duct whose base end is connected to the outlet of the take-out gutter 28;
It faces into the storage bag 38 attached to the rear of one side of the housing.

Next, its effect will be explained. A vehicle body 1 is placed over the tea ridges, and wheels 2, 4 and 5 are arranged between the tea ridges on both sides.

Therefore, depending on the height of the tea plant in the tea ridge, the winder 2
When the handle 23 of the platform 11 is rotated appropriately in one direction or the other, the groove wheels 13 and 14 of the lifting platform 11 roll on the vertical rod 6, and the groove wheel 15 rolls on the vertical rod 7 through the spring 24. While the lifting platform 11 operates in parallel along the vertical rods 6 and 7, the reaper a is raised or lowered in parallel with the lifting platform 11 , and the ground height of the reaper a relative to the upper surface of the brown furrow is adjusted. .

Next, depending on the shape of the upper surface of the brown ridge, loosen the knob bolt 26 and move the hanger 25 to the adjustment shaft 35.
If the mower a moves to the left or right as appropriate, the center of gravity of the reaping machine a shifts accordingly, and the lifting platform 11 automatically moves up or down along the vertical rods 6 and 7 while reaping. The reaper a rotates about the horizontal shaft 16, and the lateral inclination angle of the reaper a is appropriately changed to adjust the plucking angle to match the upper surface of the brown ridge. After that, tighten the knob bolt 26 and
5 is fixed to the adjustment shaft 35.

Therefore, after starting the prime mover 28, if the operator grasps the handles 31 and 32 and starts operating the machine, the machine moves forward at an appropriate low speed by the driving action of the wheels 2, and the machine casing 27 is moved forward. The rotary blade 29 strokes the top surface of the tea ridge with the bottom surface equipped with the stabilizing plate 33, and picks up the tea leaves in one half of the top surface of the tea ridge according to the shape and unevenness of the top surface.
The fresh leaves are picked by the machine casing 27, transferred to the first side by the conveyor chain 30, enter the take-out gutter 28, and pass through the blow-up duct 37 by the air blown from the blower 9. It is blown into the storage bag 38 and stored.

At that time, the operator operates the handles 31 and 32 appropriately according to changes in the shape and unevenness of the upper surface of the brown ridge, so that the lifting platform 11 can be moved to the vertical rod 6, as described above.
The reaping machine a moves up and down along the vertical rods 6 and 7, and the height above the ground is adjusted by raising and lowering in parallel. The reaper a moves up and down using the shaft 16 as a fulcrum.
The lateral inclination angle of the reaper a is adjusted so that the reaper a
Work can be performed by matching the bottom surface of the tea ridge to the shape and unevenness of the top surface of the brown ridge.

On the other hand, when the adjustment bolt 19 is rotated in one direction or the other, the horizontal shaft 16 with the support piece 18 is rotated upward or downward using the support shaft 17 as a fulcrum.
The reaper a attached to the horizontal shaft 16 is also adjusted accordingly, and the inclination angle of the reaper a in the front and back direction is adjusted accordingly.

Note that even if a clipper-type reaper is installed in place of the rotary-type reaper a, the same effect as described above will occur.

Furthermore, the device of the present invention can also be applied to a riding type tea picking machine.

In the present invention, the reaping machine mounting device for the self-propelled tea picker is constructed as described above, and the two vertical rods in the front and rear in one side frame of the gate-shaped vehicle body are used as the supports. In addition to being economical as it does not need to be installed as a separate part, the platform can be easily moved by holding the front vertical rod between the groove wheels at the front and middle of the platform and by engaging the rear vertical column of the rear groove wheel. The reaper is securely supported by the front and rear vertical rods so that it can only move up and down, and the reaper installed on the platform can only move up and down using the horizontal axis of the platform as a fulcrum, and there is no swing of the other side of the reaper backwards. , and the lifting platform with the reaper moves up and down lightly and smoothly along the front and rear vertical rods. Therefore, during the plucking operation, the operator only needs to watch the vertical movement of the reaper, making it easier to operate the reaper.

Furthermore, by operating the hoist, the height of the reaper relative to the top surface of the tea furrow can be adjusted, and by adjusting the horizontal movement of the hanger, the lifting platform automatically moves up and down along the vertical rod for reaping. The lateral inclination angle of the machine changes, allowing the reaper to be suspended depending on the height, shape, etc. of the upper surface of the tea ridge. Therefore, after that, the operator only needs to operate the handle of the reaper to finely adjust the reaper according to changes in the shape of the upper surface of the tea ridge, irregularities, curvature of the tea ridge, etc. In other words, there is no need for an assistant worker, and even a single driver can easily perform the work, which saves manpower and is convenient for handling.It also operates lightly and smoothly and always picks fresh leaves accurately. This improves work efficiency.

Moreover, it has a simple structure and can be manufactured easily and inexpensively.
